声重力波激励时的电离层的响应

Response of Ionosphere to the Excitation of Acoustic gravity Wave

由中层大气中脉冲点源激起的声重力波及中性粒子和带电粒子之间的相互作用，在小扰动下，首次得到了由于扰动引起的附加电子浓度，附加电子浓度的时间变化率，反射高度和多普勒频率漂移随着时间的变化表达式．由实验比较，证实所导出的解析表达式是正确的．

According to the theory of acoustic gravity waves caused by an impulisive point source in the middle atmosphere and the interaction between electrons and neutral particles,an expression among the parameters of additive electronic density,the rate of additive electronic density with time,reflection height and Doppler shift is obtained under the condition of small disturbance.The curve gained from the experiment is coincident with the theoretical one
